2 Definitions Light Transmission D65 (% LT): Percentage of the incident visible light that passes through an object. Solar Heat Gain Coefficient (SHGC) or g-value is the total solar energy that enters the interior of a building, divided by 100. Direct Solar Transmission (%DST): Percentage of incident solar radiation that passes directly through an object. Total Solar Transmission (%TST): The percentage of incident Solar radiation transmitted by an object which includes the direct Solar Transmission plus the part of the Solar Absorption reradiated inward. Shading Coefficient ( SC): The ratio of the total solar radiation transmitted by a given material to that transmitted by normal 3 mm glass, whose light transmission is 87%. SC=%TST/87. Light to Solar Gain Ratio (LSGR): The ratio between total light transmission (LT) and the total solar transmission (TST). Solar Transmission Lexan Thermoclear Plus 9 wall sheet is essential opaque to all wavelengths below 385 nanometers. This useful shielding property can prevent discoloration of sensitive materials placed under or behind. Solar heat gain within a building is caused by heat input from radiation emitted from the sun. Sunlight entering the building heats the air both directly and through absorption by the framework, furniture, etc. and is released as infrared energy. In combination with the insulation properties of Lexan Thermoclear sheet, this prevents heat escaping faster than it is created causing a temperature increase, the so-called greenhouse effect. The temperature can be controlled by venting, often in combination with special tinted opal white or Lexan Thermoclear SC IR which contains a proprietary additive which selectively absorbs the near infrared region of the light. Lexan Thermoclear is therefore available in many different colors or with IR additives, which both cuts down the brightness of sunlight to a pleasing level and reduces heat build up inside the building. Calculations for solar heat input through glazing are normally based on data published in The Institution of Heating and Ventilating Engineers Guide Book. These calculations are based on clear glass and correction factors or shading coefficients are then applied when alternative glazing materials are used. UV Resistance The complete Lexan Thermoclear Plus 9 wall sheet range features a proprietary both sides surface treatment designed to protect the sheet against the degrading effects of ultra-violet radiation in natural sunlight. Both sides UV protected surfaces offers advantage in economically cutting the sheet in desired shapes, and installation mistakes are minimized since both sheet surfaces may be faced outwards. Thermal Insulation The multi-wall structure of Lexan Thermoclear Plus 9 wall sheet offers significant advantages where thermal insulation is a major consideration. The hollow form provides excellent insulation characteristics with heat losses significantly lower than mono-wall glazing materials. U- or K-value range from 1.77 to 0.99 W/m 2 K. Fire Test Performance Lexan Thermoclear Plus 9 wall sheet has good fire performance against many national fire codes dependent on thickness and color; please check with the local sales office for details. Impact Strength Lexan Thermoclear Plus 9 wall sheet has outstanding impact performance over a wide temperature range, - C to +1 C, and also after prolonged outdoor exposure. As a roof glazing material Lexan Thermoclear Plus 9 wall sheet is subjected to the extremes of weather; storms, hail stones, wind, snowfalls and ice formation. Under these conditions, the product is virtually unbreakable and is able to accommodate the subsequent temperature change to sunny conditions without breaking or buckling. Please refer to the warranty for details. Warranty SABIC Innovative Plastics offers a TEN (10) YEAR LIMITED WRITTEN WARRANTY on Lexan Thermoclear Plus 9 wall sheet covering discoloration, loss of light transmission and loss of strength due weathering. See warranty for exact details. Lexan* Thermoclear*

3 Deflection characteristics of Lexan* Thermoclear* Plus 9 Wall sheet Four sides clamped: The deflection characteristics in this particular configuration are dependent upon the ratio of the support bar spacing W / L. In practice, W represents the centre-to-centre distance of glazing profiles on the width of the sheet. L represents the centre to centre distance of glazing profiles on the length of the sheet.

4 Two sides clamped, glazing bars parallel with rib structure: W = centre to centre distance of glazing profiles; L = sheet length The major factor determining the sheet deflection behavior is the distance W between the centre points of two adjacent supports. Since any length can be selected, the measurement L does not influence the overall deflection performance.

5 Four sides clamped; cold curved: In this situation sheets are cold curved and clamped at four sides in wet or dry glazing profiles. Here the cold-bending radius must be parallel to the ribs of the sheets. The ratio sheet width (W) / sheet span = 1 : >2. In practice, W represents the centre-to-centre distance of glazing profiles on the width of the sheet. Sheet span represents the centre-to-centre distance of glazing profiles on the length of the sheet. LT2UV169X: Radius R in mm Loading in N/m LT2UV9X: Radius R in mm Loading in N/m

6 Four sides clamped; cold curved: In this situation sheets are cold curved and clamped at four sides in wet or dry glazing profiles. Here the cold-bending radius must be parallel to the ribs of the sheets. The ratio sheet width (W) / sheet span = 1 : >2. In practice, W represents the centre-to-centre distance of glazing profiles on the width of the sheet. Sheet span represents the centre-to-centre distance of glazing profiles on the length of the sheet. LT2UV9X: Radius R in mm Loading in N/m Note on cold curved applications: Although the Lexan Thermoclear Plus 9 Wall sheet can be cold curved in the thicknesses 16- and mm at a radius of 175 times the thickness of the sheet, there might appear a optical distortion of the internal layers. This optical distortion will have no negative influence on the mechanical performance of the product provided that the guidelines for cold curved applications in this data sheet are correctly followed.

7 General Guidelines Storage Lexan Thermoclear Plus 9 wall sheet sheet should be stored and protected against atmospheric influences like sun, rain, etc. Care should be exercised when handling and transporting Lexan Thermoclear Plus 9 wall sheet in order to prevent scratches on the panel surface and damage to the panel edges. Cleaning Periodic cleaning using correct procedure is recommended to prolong service life. For extensive cleaning recommendations please read our technical manual. Small surfaces; gently wash sheet with a solution of mild soap and lukewarm water, using a soft, grid-free cloth or sponge to loosen any dirt or grime. Do not use any corrosive materials or chemicals to clean Lexan Thermoclear Plus 9 wall sheets. Chemical Resistance Neoprene, EPT or EPDM rubbers with an approximate Shore Hardness of the A65 are recommended. When using glazing compounds it is essential that the sealant system accepts a certain amount of movement to allow for thermal expansion, without loss of adhesion to the frame or sheet. Silicone sealants are generally recommended for use with Lexan Thermoclear Plus 9 wall sheet. It is strongly advised when using sealing to check before compatibility before use. Sawing Lexan Thermoclear Plus 9 wall sheet can be cut easily and accurately with standard workshop equipment. This includes common circular, hand and hacksaws. Saw dust should be blown out of the channels using clean compressed air. Circular saw blade should be fine-toothed panel blades. When hand or power hacksaws are used, the sheet should be clamped to the worktable to avoid undesirable vibration. Thermal expansion allowance Since Lexan Thermoclear Plus 9 wall sheet has a greater linear thermal expansion coefficient than that of traditional glazing materials, care should be taken to allow for free expansion of the sheet to prevent bowing and internal thermal stress. Thermal expansion allowance must be made for both the length and width of the Lexan Thermoclear Plus 9 wall sheet. In general, thermal expansion of the sheet is approximately 3 mm per linear meter.
